The compressed point format includes the least significant bit of the second coordinates in the first byte to know the orientation , so that is why the index is incremented one unit when dealing with compressed curves .  Otherwise the function ccec_compact_import_pub_size receivesthe wrong number, expecting always a number greater in just one unit.
